METHOD 0F ANTI MACHINE FOR MAKING CGLOBED PATTERYED LINOLEUM,- OIL-ELQTH LIIJCRUSTA, Alf-ID THE LIKE.

To all 'whmn it 7110; com-("1 7e Be it lcnown that l, CARL Jenn, menufactorcr. subject of the l'ling'o'f Prussia, residing at Berlin. Prussia German Em: pire, have invented certain new and useful Improvements in Methods of and Machines for Making Colored ?atterne' ;l Linoleurrn Oil-Cloth, Lincrnsta, and the like, of which the following is a specification.

The present method for making colored patterned linoleum, oil-cloth. lincrusta-or the like consists therein that at each operstion a quantity of raw material oi color corresponding to the respective equally colored sections of if iesigii is supplied onto 1 once equal to the length of the design and. compressed hy'mee-nsoii a pressure roller having; a rsisedport on corresponding to the equally colored section or the design, while behind the said roller the loose, not compressed remainder of the raw material is sucked away.

as Hlllfly compressing roifle difierent colors in the design. Go the one side Of'llllQSG rollers is the mouth. piece of a. suction pipe.

In the accompanying drawing constructional form of a machine is exen pl1fied, in which the hacking travels in horizontal plane over a pressure-table, and. the eon:- prcssing rollers revolve in stationary hear- 1i: gs.

Of the design shown inFig. 1' it is as-.

full black section (heart of the flower) 4 is yellow.

. In carrying out the process, four dillerently colored raw naznterials; corresponding to the four colors of. the pattern are fed to a set. of compressing rollers a a a a each difierently. colored raw material being "acted on'by a separate roller. The circumference of each of'these rollers is equal to the length L of the design (Fig. 1). ()n

respective sections of the design 1,2,3, l (Figs. 2., 3 4;, 5). By these rollers the raw meterlal 1S compressed, while the rethis circumference of the said rollers. are 1321 886. portions, which correspond to the meinder, which has not been compressed is.

sucked sway. The backing b'is' drawn in the direction. of the arrow I in Fig. 6, For insuring that the travel of this backing correspondsv with the sections of the design the backing is drawn by means of a chain c (Fig. 8), on which grippers having the shape of tongs (Z, 6, are provided, which are automatically closed by a bar f on the machine, the legs (Z of the tongs entering into a longitudinal slot .17 in the bar, where "by the legs (Z, and thereby alsothe legs 0 are pressed. together. In the constructional form of the n'mchine-exemplified in the .accompanying drawing vthe compressing roll' ers are arranged at a distance from each other equal to thelength oi the design, and:

they revolve the same velocity as the backing travels. In front of eachof these rollers, seen in the direction of the arrow I is a mouthpiece it for the supply of the raw material, behind. the roller the suction nozzleforcarrying off the material which hasv not been compressed bythe roller. 'The supplying. and carrying off arrangements are the same for each roller, whereforei hereinafter the arrangement for the roller a alone shall be described. 1

Over the roller a is situated the container it for the gray material, which container is shut off from the feed hopper u by means ofs'v slide w. Beneath the slide w is arranged. a. sluice with two hermetically closscraperl. The raw material thus drops onto gether Withfthe machine.

the backing 7) and is fed under the roller a At the same time the suction is produced behind the roller, as the fan is started. to

The raw material Which has not been compressed passes through the nozzle 15 and the pipe {1 back into the container 1:,

In order to prevent the raw materiel be: ing carried along in it the mouth of the pipe 9 is arranged at a lower level than that of the pipe p. Furthermore a bafiling plate 3 is provided in the chamber 06 and. a filter e in the pipe 39. When the raw material has accumulated over the slide to about the level CD, Which may be controlled through an inspection Window, the slide at of the sluice is opened. The accumulated raw material then drops into the sluice, whereupon the upper slide m-is closed and the lower sliden is opened. lhe provision. of the sluice thus insures the production of a continuous vacuum in the chamber. as. By the roller c the gray raw material. is thus applied to the backing in a compressed condition and in accordance With the design, and the loose not compressed raw material. has been removed by suction behind the compressing point. After the backing is then advanced by the length of the design the green raw material is suppliedto .the roller a and compressed thereby, While the remaining not compressed surplus is again sucked away, and so on. When at last the last section of the design hasbeen compressed. by roller a the web of linoleum is removed from the machine and may, if necessary, be again rolled in a calendering machine.

It is necessary that the portions on the rollers are of a considerable height. This is however practically impossible with metal rollers, owing both to the difficulty in manufacture and the high cost. It is therefore suggested to make the rollers of artificial stone, consisting of a mixture of cement, sand and magnesia in known manner. In such material a sufi'iciently high relievo design may be produced by aid of sand. blast and suitable template.

It is not imperative, that the rollers are arranged at a pitch equal to the length of Leonie? 1 the design. For reducingthe manufacturing cost of the machine it Will be advisable to make the machine shorter and to arrange the rollers at a pitch equal to half the length. of the design, which arrangement, however, provides, that the rollers following the first roller alternate relatively to the first by half'their circumference.
